The 10-euro coin features two sentences from the third chapter of Ulysses streaming from Joyce's head. The actual passage reads:

Ineluctable modality of the visible: at least that if no more, thought through my eyes. Signatures of all things I am here to read.

But on the coin it reads:

Ineluctable modality of the visible: at least that if no more, thought through my eyes. Signatures of all things that I am here to read.

Spot the difference? Yeah, neither did the bank; there's an extra "that" in the second sentence of the coin text. The bank says the limited-edition coin "is an artistic representation of the author and text and not intended as a literal representation," but it's nonetheless sending a message with each coin noting the misquote.
